Advantages of Deublin Swivel Joint:

Cooling liquid or MQL single channel

Closed seals for transmission lines and similar applications

• Full flow design without obstacles to chips or debris

Bearing support with threaded rotor for easy installation

Deep groove centripetal ball bearing for smooth operation

Maze system and large ventilation holes to protect ball bearings

Balanced mechanical seals made of silicon carbide have a long service life even under harsh operating conditions

Anodized aluminum casing and stainless steel rotor for corrosion resistance

The characteristics of the Deublin rotary joint:

1. Pressure joint:

The pressure joint is sealed by pressure. This classic technology requires relatively high torque and is only suitable for low pressures (<250 psi or 17 bar).

2. Plastic seals:

Plastic rotary joints use customized or commercially available "soft seals" made of polymers or elastic systems for specific applications. Because they are lightweight, they exhibit high torque, heat generation, and wear rates.

3. Static pressure seal:

Static pressure rotary joints provide precise tolerances and non-contact sealing, requiring no maintenance. They have a rotating element suspended on a fluid membrane that continuously circulates at a very low flow rate, which helps to prevent the speed of these joints from being too high.

4. Mechanical seal:

The mechanical seal rotary joint reduces the wear and heat generation of the sealing components, and has extremely high accuracy over a wide pressure range. They have a pressure resistance of up to 140 bar and can operate at temperatures up to 40000 RPM. They can also be designed in different ways based on the intended use of the joint.
